AUTOMATIC STOP FOR BARBING-IVACHINES.

" p SPECIFICATION forming part of Letters Patent No. 408,737, dated August 13, 1889.

Application filed December 13, 1888. Serial No. 293,527. (No model.)

To a/ZZ whom it may concern:

Be it known that I, ANDREW M. MUNSON,

a citizen of the United States, residing at.

Lee, in the county of Lee and State of Illinois, have invented certain new and useful Improvements in Automatic Stops for Vire- Barbin g Machines; and I do hereby declare the following to be a full, clear, and exact description of'thepinvention, .such as will enable others skilled in theV art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or iigures of reference marked thereon, `which form a part of this speciiication.

My invention has reference to automatic stops for wire-barbing machines; and it consists more especially of certain novel mechanism by means of which any casual tangling or catching of the Wire in the process of uncoiling prior to the barbing thereof can be utilized to automatically shift the belt of the line-shaft or counter-shaft from the drivepulley to an idle-pulley, and thereby stop the machine.

It is well known that in the manufacture of barb fence-wire the main strand or strands are fed to the barbing mechanism in one direction through the machine, while the Wire which is cut up for barbs is fed to such barbing mechanism at right angles to the firstnamed feed. The smooth wire, intended both for the main strand and for the barb material, is placed in a coiled condition upon the reels-those for the main strand at the end of the machine or under it and that for the barbs at the side thereof.

The style of fence-Wire most generally used get-her, on one or both of which the barb is seated at desired intervals. A few kinds of wire consisting of a single strand are used to some extent.

My invention is adapted for use with any kind of wire-barbing machines without regard to the number of 'strands of which the finished product may consist.

different kinds, and has its place and operation previous to and independent of the process of barbing, I do not deem it necessary to show or describe any of the mechanism involved in the process of barbing. All ofthe machines are driven from a counter or hne I shaft, upon which latter there are seated in close proximity a driving-pulley and idler for each machine, and such machine is stopped and started by shifting the driving-belt which connects the driving-pulley upon the machine with the aforesaid driving-pulley or idler upon the line or counter shaft from one to the other of the last-named pulleys.

My invention has for its scope means for causing any casualV stoppage of the uncoiling of the wire from the feeding-reels to automatically shift said driving-belt from the driving-pulley on the counter or line shaft to the idler upon said shaft, and thereby arrest for a time the further operation of the barbing-machine.

In the drawings the reels from which the plain wire is uncoiled in the process of barbing areshown seated upon the fioor which supports the barbing-machine, and the lineshaft referred to is journaled beneath the floor; but with obvious subordinate changes my invention can be readily adapted to any special location of the machine relative to the line or counter shaft.

In the drawings, Figure l is a side elevation of the parts involved in my invention. Fig.'2 is a plan of one of the reel-standards detached,.showing the pivotal attachment to the floor. Fig. 3 is a modification, and Fig.

4 is a plan, of the reel-standard used therewith.

A is the floor.

-B is the counterorline shaft suitably joui'- naled to the iioor on the lower side thereof, upon which are seated rigidly the driving-pulley O and idler D, from which extends upward the belt D', which drives the barbing-machine.

E is a rod loosely carried in bearings E', suitably attached to the hangers of the lineshaft B. The rod E is supported parallel with the line-shaft B, and is provided with the usual projecting arms F to engage the belt D and shift the latter optionally from pulley O to pulley D, or Vice versa.

G. is a vertical lever, suitably fulcrumed upon the iioor A and extendin g down through the latter, and having its lower end pivotally IOO attached to the rod E, so that the oscillations of said lever in the line of the shaft B will cause the rod E to reciprocate in bearings E in a direction parallel with the shaft B, and cause the arms F to engage the belt D and shift the latter from one to the other of the pulleys C and D.

The parts just described are abstractly old, and can be varied to suit different situations; but my invention consists more particularly in mechanism, which I will now proceed to describe, for causing any casual stoppage of the uncoiling of the wire to oscillate the lever G.

H is one of the wire-reels which carries the plain wire to form the strand of the iinished product. There are usually two of these, sitting side by side; but inasmuch as the construction and operation of each of said reels is a duplicate of that of the other I do not deem it necessary to show or describe more than one of them. From the bottom plate 1 there centrally arises a vertical standard 2, and from the upper portion of the latter there is loosely suspended the horizontal revolving frame 3, upon which the coiled wire 4 is laid, and which revolves horizontally on the standard 2 in the uncoiling of said wire. The frame 3 is supported pivotally on stai'ldard 2 by the central hole 1G in the upper end of said frame, being slipped down over the upper end of said standard and sustained loosely upon an annular shoulder or collar 17, formed 011 said standard. The wire 4 is drawn from the frame 3, as needed by the machine, bythe usual feed-rollers. (Not shown.) rl`he plate 1 is supported slightly above the floor A by blocks 5, attached at their under side to the lioor A, and having converging angular upper sides, forming crests or apiees 6 in a line perpendicular to the line of the feed of the wire. The main portion of the plate 1 normally rests upon the plane 7 of block 5 farthest from the barbing-machine, and this has the effect of throwing the standard 2 out of the perpendicular and from the machine, where it is held by the weight of the wire 4. In the base of the plate l, directly over the crests 6, are formed slots S, through which are passed, respectively,vertical short bolts 9 into the blocks 5, whereby said plates are held upon said blocks, and at the same time permitted to rock on the crest G of the blocks 5. On the upper ,end of the standard 2 is removably and loosely sleeved one end of the arm 10, which projects above the frame 3 toward the barbingmachine, and is bent downward at its other end, enlarged, and provided with a vertical slot 11, through which the wire 4 is drawn by the rollers aforesaid. The slot 11 is of such width as to permit the free passage of the wire 4 when there are no knots or kinks on the latter which would interfere with the barbin g process; but if there are such kinks or knots the same catch against slot 11, when the fur therdrawin g of the wire 4 by the feed-rollers aforesaid will have the effect of driving or tilting the standard 2 on the crest 6 toward the barbing-machine, and the same tilting eifect is produced in case the wire upon the frame 3 becomes tangled from any reason and ceases to uncoil readily. The standard 2 projects down through the plate 1, and at its lower end is connected by a rod or rope .I to the lever G above the fulcrum of the latter. It is obvious that the tilting of the upper end of the standard 2 toward the barbing-machine will have the effect of throwing the lower end of said standard away from the barbing-maehine, and by means of the rod or rope .I drawing the upper end of the lever G also away from the barbing-machine, and thereby shifting the belt D from the-drivepulley C to the idler D, the parts assuming the position indicated by dotted lines in Fig. 1 and arresting the motion of the machine.

In case the slot 11 shall become worn laterally by the passage of the wire 4 therein, the sides of said slot can be proportionately driven together. The upper end of the arm 10 is loosely seated on the standard 2, in order to be readily removed to permit the succeeding coils of wire 4 to be placed upon the -frame 3, and also to permit a slight vertical oscillation of said arm to further adjust the slot 11 to the altitude of the unwinding wire. If preferred, the arm 10 can be placed on the standard 2 below the frame 3, in which construction there will be no necessity for the rcmoval of said arm. A knot formed on the last end of the wire will engage slot 11 and stop the barbing-machine when the coil is exhausted.

After the rocking seats of the wire-reels II are once shown as a means of moving the shifting-lever G, various modications in the method of such seating will readily suggest themselves, and in the side reel K, which carries the wire from which the barbs are cut, I show another mode of seating and rocking said reel. In the latter construction the front edge of the plate 1 is pivotally connected at two points 15 to the floor A, and a staple ,l2 is driven into the floor under the reel K, near the outer edge of the latter, and a rope or chain 13 is attached to4 the under side of the rear portion of the plate 1 of reel K, and, after passing through the staple 12, is passed inward and around a pulley L, vertically seated on the floor A, and from thence attached to the lever G above the fulcrumpoint of the latter. A small pulley or sheave can be substituted for staple 12.

It will be seen that the inward tilting of the standard 2 of the reel K (which tilting is ej.- feeted in the same manner as that described for the reel II) will have the effect of drawing outward upon the rope 13 and of oscillating the lever G, with the same effect as before described in reference to reel Il.

As in some constructionsthe lever G, in or der to shift the belt Dl upon the idler D, would be required to move in an opposite direction from that heretofore described, I show athird IOO IIO

reel M, (see Fig. 3,) pivoted centrally at its base, substantially as heretofore described in reference to reel II, but having attached at its rearend a rope or chain 14, which passes at that point down through the tloor A, and over a pulley N, horizontally pivoted under iioor A, and from thence is extended and attached to the lower end of the lever G, whereby the inward tilting of the reel M (accomplished substantially as described in reference to reel H) has the' eect of drawing outward on the lower end of the lever G and oscillating the latter in the direction opposite from that heretofore described.

The rocking seats of the wire-reels can be constructed in any of these or in various other modes, and the attachment thereto of lever G can be suitably accomplished, and the fulcrumed seats of said reels can be varied in or out to adjust the rocking of said reels to anyl desired tension of the Wire t.

What I claim as my invention, and desire to secure by Letters Patent of the United States,

1. In an automatic stop for wire-barbing machines, the combination of the standard 2, inclined from said machine and provided with the frame 3, the base-plate 1, and the block 5, interposed between said plate and the ioor A, substantially as shown, and for the purpose described.

2. In an automatic stop for wire-barbing machines, the combination of .the base-plate 1, standard 2, seated in said plate and provided with rotating frame 3, and block 5, interposed between said plate and iioor A, and provided with upper face 7, sloped down- Ward and from said machine, and adapted to support said plate and normally incline it from said machine, substantially as shown, and for the purpose described.

3. In an automatic stop for wire-barbing machines, the combination of a rocking wirereel I-I, a feed-arm 10, provided with slot 11, a shifting-lever G, and means, substantially as shown, for communicating the oscillations of said reel to said lever, substantially as shown, and for the purpose described.

4. Inan automatic stop for wire-barbing machines, the combination of a wire-bearing reel II, provided with a rocking base 1, a guide-arm 10, provided with slot 11, a beltshifting lever G, suitably connected to driving-belt D', and a rod or rope J, connecting said ,reel to said lever, substantially as shown, and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

ANDREW M. MUNSON.
